Abstract
This research explored design of optical mouse sensor as position measurement system
for a magnetorheological (MR) spherical brake. Spherical MR-brakes and other spherical joints
have been designed by various researchers. Due to the 3D motion of the handle attached to the
ball in the joint, it is quite challenging to measure the angular position of the handle. The most
common approach is to use a gimbal mechanism. However, this makes the overall device design
bigger with several moving parts. In this research, the primary goal was to develop a prototype
spherical MR-brake that incorporated optical mouse sensors for real-time position measurement
of the handle. It was found that the sealing performance improved by using cotton cloth to
absorb MR-fluid. A new coil was also designed to generate magnetic field in a small space and
the size of the MR-brake was reduced. Strain gauges were used to build a force measurement
system.
